4-20ma Et2715 Current And Voltage Calibrator Machine Weight: 0.35 Kilograms (Kg)

4-20mA ET2715 Current and Voltage Calibrator is a handheld calibration instrument with high precision, high resolution and high reliability that integrates output and measurement of V, mV, mA and Hz signals. The meter adopts large liquid crystal display with clear reading, and it also has adjustable back light source and automatic shutdown function. The meter can be supplied by dc or ac power supply, which is more convenient to use.
